Import Namespaces

First, import the necessary namespaces into your C# project to access the functionalities of GroupDocs.Merger:

using System; 
using GroupDocs.Merger;
using System.IO;

Follow these steps to merge ZIP files programmatically:

Step 1: Set Output Directory and Output File Name

Create a string variable to define the output directory where the merged ZIP file will be saved and specify the name of the output file.

string outputFolder = "Your Output Directory";
string outputFile = Path.Combine(outputFolder, "merged.zip");

Step 2: Load and Merge ZIP Files

Initialize a Merger object with the path of the source ZIP file you want to merge.

using (var merger = new GroupDocs.Merger.Merger("Path_to_Source_ZIP"))
{
    // Add another ZIP file to merge (optional, you can add multiple)
    merger.Join("Path_to_Another_ZIP");
    
    // Merge ZIP files and save the result
    merger.Save(outputFile);
}

Replace "Path_to_Source_ZIP" and "Path_to_Another_ZIP" with the paths to the ZIP files you want to merge.

Step 3: Save Merged ZIP File

After merging, the merged ZIP file will be saved at the specified output path (outputFile).

Console.WriteLine("\nZIP files merge completed successfully. \nCheck output in {0}", outputFolder);
